SEATTLE — Nobody knows when Aaron Hicks will come off the disabled list. But when all the Yankees outfielders are healthy, Clint Frazier will be the odd man out.

“Send Frazier out,’’ general manager Brian Cashman said via phone Thursday when asked how the outfield picture will unfold when Hicks returns. “But Hicks isn’t doing anything yet, so that is down the road.’’

Hicks hasn’t played since June 25 because of a right oblique injury that has been slow to heal.

As for Frazier, Cashman and manager Joe Girardi have been impressed with his play since getting called up.

“He has been great and earned everyday playing time,’’ Cashman said of Frazier, who wasn’t in the lineup Thursday night against Felix Hernandez.

“He has really played well. I think he has played well offensively, he has ran the bases well and played well defensively,’’ Girardi said of Frazier, who is hitting .298 (14-for-47) with three homers, eight RBIs and a .944 OPS. “He has been in right and left and we have asked him to move around. His at-bats have been really good.’’

Ben Gamel was named the International League MVP last season when he was with Triple-A Scranton/Wilkes-Barre before he was dealt to the Mariners for right-handers Jio Orozco and Juan De Paula.

Gamel, who went 1-for-5, is batting .317, which is five points better than Judge.

“I thought he was a kid who had some talent. I don’t think any of us saw what he is doing this year,’’ Girardi said of the left-handed hitting outfielder. “But there were a lot of people in our organization who were really high on him.’’
